先看看效果：

用极少的代码实现了动态详情及二级评论的数据获取与处理和 UI显示与交互，并且高解耦、高复用、高灵活。

动态列表界面MomentListFragment支持下拉刷新与上拉加载和模糊搜索，反复快速滑动仍然非常流畅。

缓存机制使得数据可在启动界面后瞬间加载完成。

动态详情界面MomentActivity支持 (取消)点赞、(删除)评论、点击姓名跳到个人详情等。

只有1张图片时图片放大显示，超过1张则按九宫格显示。

用到的CommentContainerView和MomentView都是独立的组件，既可单独使用，也可用于ListView或添加至其它ViewGroup等。

CommentContainerView复用

CommentContainerView.java


setOnCommentClickListener    : 设置点击评论监听
createView           : 创建View
bindView            : 绑定数据并显示View
setMaxShowCount         : 设置最多显示数量，超过则折叠
setComment           : 设置评论
addCommentView         : 添加评论View

由于这个项目使用了ZBLibrary快速开发框架，所以实现仿QQ空间和微信朋友圈的这种复杂界面只用了极少的代码，并且高解耦、高复用、高灵活。

服务端是用APIJSON(Server)工程快速搭建的，客户端App和服务端通过APIJSON-JSON传输结构协议通信，非常方便灵活，省去了大量的接口和文档！

今年RxJava特别火，在北京市场几乎是必备技能，所以我还把这个项目做了个RxJava版本，欢迎交流和指教。

实现UI的Java类:


MomentListFragment       395行       动态列表的获取和显示
MomentActivity         616行       动态和评论列表的获取、显示和交互(评论和删除评论等)
MomentAdapter          67行        动态列表的显示
CommentAdapter         82行        评论列表的显示
MomentView           495行       动态的显示和交互(各种跳转、点赞、删除等)
EmptyEventGridView       56行        动态里图片的显示和交互(触摸空白处传递触摸事件到内层View)
PraiseTextView         129行       动态里点赞用户的显示和交互(点击姓名跳到个人详情，点击整体跳到点赞的用户列表界面)
CommentView           153行       一级评论(头像、姓名、内容)的显示和交互(回复、删除等)，添加二级评论列表
CommentContainerView      172行       二级评论列表的显示和交互(查看全部等)
CommentTextView         122行       二级评论(姓名、内容)的显示和交互(回复、删除等)

实现UI的XML布局:


moment_activity         47行        动态和评论列表的显示
moment_view           148行       动态的显示
comment_view          87行        一级评论(头像、姓名、内容)的显示
comment_container_view     20行        二级评论列表的显示
comment_item          10行        二级评论(姓名、内容)的显示

为什么没有实现MomentListFragment对应的XML布局？

因为MomentListFragment继承BaseHttpListFragment，内部用XListView作为缺省列表View，所以可以不用自己实现了。

实现数据获取、提交和处理的Java类:


HttpRequest           +175行       数据的获取和提交(getMoment,...,deleteComment)
CommentUtil           140行       单层评论和和二级评论的处理
Comment             56行        评论数据
CommentItem           99行        评论的显示和交互数据
Moment             43行        动态数据
MomentItem           272行       动态的显示和交互数据
User              103行       用户数据

(注:未列出的代码文件要么和动态无关，要么APIJSON或ZBLibrary已提供。server.model里的类由服务端提供)
